Fine text on Prescription Eyeglasses

This is a discussion on Fine text on Prescription Eyeglasses within Shifting gears, part of the Around the Corner category; Friends I just ordered a new pair of glasses the other day.
My eyes need prescription correction for both distance ...

It has been recognized that it would be advantageous to develop a method and device for accurately determining the location of an auxiliary lens in a multifocal eyeglass lens. In addition, it has been recognized that it would be advantageous to develop a method and device to allow an eyeglass patient to view the location of an auxiliary lens in a pair of eyeglass frames before the production of the lens.
The present invention provides an eyeglass lens applique device for determining placement of at least one auxiliary lens within an eyeglass lens. The lens applique device can include a sheet of plastic that is removably disposable on the eyeglass lens. The plastic sheet can cling to the eyeglass lens by specific or mechanical adhesion. The plastic sheet can also include an outline of at least one auxiliary lens, and scale markings to show distance from the outline of the auxiliary lens to an approximate peripheral edge of the eyeglass lens.
In another aspect, the outline of the auxiliary lens on the plastic sheet and an area enclosed by the outline can be translucent.
The present invention also provides for a method for determining an auxiliary lens location for an eyeglass lens including placing a pair of eyeglasses on a patient. The eyeglasses can have a frame and a pair of lenses within the frame. An applique can be applied on at least one of the eyeglass lenses. The appliquÎ* can include an outline of an auxiliary lens and a distance scale. The placement of applique can be adjusted based on feedback from the patient with respect to the location of the outline of the auxiliary lens on the eyeglass lens. A scale on the applique can be observed in order to determine a distance from the outline of the auxiliary lens to a perimeter of the eyeglasses frame or lens and the distance can be recorded.

As illustrated in FIGs. 4a-5, an eyeglass lens appliquÎ* device, indicated generally at 200, in accordance with another embodiment of the present invention is shown for use in determining placement of at least one auxiliary lens within an eyeglass lens 12. The lens appliquÎ* device 200 can be similar in many respects to the lens appliquÎ* device 10 described above and shown in FIGs. 1-2. The lens appliquÏŒ device 200 can include a plastic sheet 220 having an outline 24 of an auxiliary lens and scale markings 50.

Quote:

Since both the right and left lenses 12 in a pair of eyeglasses may have different placement locations for an auxiliary lens, each lens 12 can be marked with its own appliquÎ* device 200.

From what I gather, the markings lie on a transparent plasctic coating on your lens. The indication 200 indiates bi-focal (300 indicates tri focal) and the other marking are created with respect to your prescription and point of changeover of lens, with respect to your physical level/height of vision.

Your optician was right. That is your addition for your presbyopia error. This has to be added to your distance vision, watch closer towards the nose bridge and you will be able to see a similar logo for the brand of the lens.

You can try blowing on the lenses and I am sure you will be able to identify a water mark to showcase the authenticity of the coating.

I'm sorry for re-opening a dormant thread. I did not want to open a new one for the question that I have.

I have been prescribed to wear glasses by my eye doctor. I have one since 2 weeks. The glasses are made of anti-reflection material. What I find strange is that when I take my glasses off after wearing them for an hour or so, my eyes become a bit blurred. After some time, my eyes turn normal. Is this natural?

How can I make sure that my glasses have the exact power that I was prescribed for? I have short-sightedness on one of my eyes. Is there a way to check my glasses if they have been calibrated for the correct power that I was prescribed?

This is natural. Your eyes take some time to adjust when you put on or take off your glasses.

You can get that checked with the same doctor who prescribed the glasses. They run few tests to check if the power is same as prescribed. Most doctors actually recommend you to get the glasses checked after you get them.
